Description

Technical Field

[0001] The invention relates to the technical field of steel component butt jointing, in particular to a steel component butt jointing device for steel structure engineering construction. Background Art

[0002] The steel component docking device used in steel structure construction is a mechanical equipment designed for efficient and accurate connection between steel components during the construction process of steel structures. It integrates precise adjustment, support and power transmission systems, and can stably fix and adjust the position of steel components during construction to ensure accurate alignment of docking surfaces. The device can flexibly adjust the docking angle and distance through manual operation to meet the needs of steel components of different shapes and sizes. Its use greatly simplifies the docking process, improves construction efficiency, reduces labor costs and potential errors, and ensures the overall quality and safety of steel structure projects.

[0003] The steel component docking device widely used in the current steel structure engineering construction generally relies on the electric control system for operation and control. Although this electric control method shows significant advantages in improving the docking efficiency, accuracy and degree of automation, the complexity of the electric control system makes it particularly difficult to quickly locate and troubleshoot the fault point when the equipment fails. Once the electric control system fails, professional technicians are often required to conduct in-depth inspection and maintenance, which not only increases the maintenance cost, but also may cause the equipment to shut down for a long time, directly affecting the construction progress and delaying the overall construction period. In addition, under certain circumstances, such as power outages and other emergencies at the construction site, the steel component docking device operated by the electric control will completely lose its working ability and will not be able to continue to perform the docking task. This high dependence on external power supply undoubtedly increases the uncertainty and risk in the construction process and poses a potential threat to the smooth implementation of the construction plan. To this end, we propose a steel component docking device for steel structure engineering construction. Summary of the invention

[0033] Furthermore, the first transmission mechanism 1, as the core power source, drives the two displacement mechanisms 4 to move in the horizontal direction, and drives the two second transmission mechanisms 6 to operate at the same time. During the movement of the displacement mechanism 4, the inner support mechanism 5 inside the displacement mechanism 4 performs inner support positioning on the steel pipe 11. When the steel pipe 11 reaches the docking position, the second transmission mechanism 6 drives the inner support mechanism 5 to expand to ensure the stability of the docking of the steel pipe 11. At the same time, the adjustment mechanism 7 outside the first transmission mechanism 1, driven by the second synchronization mechanism 8, drives the welding mechanism 9 to move accurately to the welding point to complete the welding docking of the steel pipe 11. The various mechanisms are tightly mechanically connected. Mechanical connection and power transmission are realized to realize efficient and accurate butt joint and welding of steel components. Each mechanism of the device adopts modular design, which is convenient for quickly troubleshooting the cause of the fault in case of fault. The device abandons the traditional expensive electric control mechanism. Only the conductive slip ring 903 in the welding mechanism 9 is an electrical device, and the rest are mechanized and manually operated, which greatly reduces the failure rate.

The base 102 has first bearings 103 fixedly sleeved at the lower parts of the two sides of the center away from each other, and the inner rings of the two first bearings 103 are fixedly sleeved with spline shafts 104. The base 102 has second bearings 105 fixedly sleeved at the upper parts of the inner centers of the two sides away from each other, and the two second bearings 105 on one side and the two second bearings 105 on the other side are fixedly sleeved with first positive and negative threaded screws 106.

First sliding grooves 1010 are provided at the upper centers of the two inner walls of the base 102 that are far away from each other, and a driving hand wheel 10 is fixedly connected to one end of the spline shaft 104.

[0035] Furthermore, the first transmission mechanism 1 is the basis of the entire docking device. It supports the entire device through four columns 101, and realizes the lateral movement of the displacement mechanism 4 through the spline shaft 104 and the first positive and negative screw rod 106 in the base 102. The driving handwheel 10 transmits kinetic energy through the spline shaft 104. At the same time, the first synchronization mechanism 2 and the first drive mechanism 3 work together to ensure that the two first positive and negative screw rods 106 rotate synchronously, driving the displacement mechanisms 4 on both sides to move synchronously, thereby realizing the preliminary positioning of the two steel pipes 11. This design realizes the preliminary centering of the steel pipe 11, laying the foundation for subsequent internal support and welding work. At the same time, the mechanized manual operation method simplifies the control system, reduces the failure rate, and improves the reliability and stability of the equipment.

The sides of the two first connecting columns 307 that are away from each other are fixedly connected to the first hand wheels 308.

[0039] Furthermore, the first drive mechanism 3 transmits power from the first hand wheel 308 to the first worm 203 through the combination of the support rod 301, the auxiliary drive wheel 302, the main drive wheel 304 and the drive belt 305, thereby driving the first synchronization mechanism 2 to operate. The protective cover 303 and the sixth bearing 306 provide necessary support and protection.
